s. E. BRETT ET AL TURRET GUN MOUNT Filed June 28, 1934 P mu n w ET vb.mE E m ma SBJ E Patented Jan. 5, 1937 UNITED STATES PATENT OFFKIETURRET GUN MOUNT Sereno E. Brett, Portland, reg., and George H. Rarcy,Fort Benning, Ga., both United States Army (Granted under the act ofMarch 3, 1883, as

amended April 30, 1928; 370 0. G. 757) The invention described hereinmay be manufactured and used by or for the Government for governmentalpurposes, without the payment to us of any royalty thereon.

This invention relates to a turret gun mount.

The purpose of the invention is to provide a turret gun mount havingsuflicient stability to carry a gun of the light artillery type in whichthe barrel moves in recoil and counterrecoil. In order to employ aturret of the smallest possible dimensions the gun mount is so arrangedthat it may be conveniently controlled from a position below the mount.

With the foregoing and other objects in view, the invention resides inthe novel arrangement and combination of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein disclosed maybe made within the scope of what is claimed without departing from thespirit of the invention.

A practical embodiment of the invention is illustrated in theaccompanying drawing, wherein:

Fig. 1 is a plan view partly in section of a turret with roof removedequipped with the improved gun mount.

Fig. 2 is a longitudinal sectional view through the turret, parts beingin side elevation.

Fig. 3 is a view in rear elevation of the gun mount without the gun andcradle.

Fig. 4 is a view in side elevation of Fig. 3, parts being in section.

Fig. 5 is a view in side elevation of the cradle.

Fig. 6 is a rear end elevation of the cradle.

Referring to the drawing by characters of ref erence there is shown arotatably mounted turret comprising a base ring 5, side wall 6, and aroof or cover I. The side wall is formed with an opening 8 which isframed in the interior of the turret by a shield 9 secured to the sidewall by screw bolts ID.

A pair of spaced brackets H-l I, each secured to the base ring 5 and tothe cover I, as by screw bolts I2, are positioned on diametricallyopposite sides of the turret for the purpose of providing balance andstability. The intermediate portion l3 of each arm is ofiset inwardlyand includes an arm I4 projecting towards the opening 8 in the sidewallof the turret. The upper face of each arm is provided with ahalf-bearing l5 (Fig. 4)

for receiving one of a pair of trunnions l6l6 extending horizontallyfrom a cradle support l1. Each trunnion is confined by a cap [8 securedin place by bolts Hi.

The cradle support I! is in the form of a substantially square framewithin which a cradle 20 (Fig. 6) is supported by vertically extendingtrunnions 2l2l threadedly secured in the cradle support. The cradle isformed with doubletapered side walls 22-22 to avoid interference withthe cradle support when it is moved about its trunnions duringtraversing. The cradle includes a pair of guides 23-23 for slidablysupporting a gun barrel 24 that extends through the opening 8 in theturret. The cradle also includes a forwardly extending guide block 25and the cylinder 26 of a recuperator mechanism which is associated withthe sliding barrel and functions in the usual manner to check recoil andrestore the gun into battery. The guide block 25 and (1 cylinder 26 alsoproject through the opening 8 of the turret.

A hemi-spherical mantlet 26 disposed within the turret is fitted on andcarried by the guide block 25 and cylinder 26 of the cradle so that itmoves with the cradle and has a close fit against the shield 9. Themantlet is formed with an aperture 21 for the gun barrel and with anaperture 28 for a periscope sight 29 carried by the cradle.

A bracket 30 depending from the wall of the turret carries a seat 3| fora gunner. A depending control member 32 carried by a non-recoiling partof the gun, for example by the cradle, has a shoulder-piece 33 and ahand-grip 34 adapted to be engaged by a gunner occupying the seat 3|.The gunner by moving his body thereby exercises control of the gun inazimuth and elevation. The means for rotating the turret is notdescribed as it forms no part of the present invention.

We claim.

In a gun mount, a turret comprising a base ring, a wall with an opening,and a cover, a pair of brackets positioned on opposite sides of theturret and each secured to the base ring and cover, each bracket havingan arm extending towards the opening in the turret, a gun cradle supporttrunnioned in the arms of the brackets, a gun cradle trunnioned in thecradle support.
